Pimoroni pHAT DAC pin use

Hi,

I’ve setup a Raspberry Pi B with Shairport to AirPlay music to my speakers. Works a treat, however the audio quality is poor and volume is low. I’m therefore looking to add external sound to fix both these issues.

Also considering replacing the Pi B with a Pi Zero.

Problem is I’m also using GPIO to turn my speakers on and off via a relay.

I was wondering if the Pimoroni pHAT DAC used all the pins? If not, which ones are available for other use?

Thanks for you help!

It uses the pins detailed here: http://pinout.xyz/pinout/phat_dac

Plus 5v power, and ground of course.

pHAT DAC supplies a line-level output, so it likely wont help for your low volume problems- that’s really down to the amplifier to solve.

Thanks! I’ve placed an order with an Australian supplier.
